帮小弟看下c++指针访问成员函数的错误吧

[telnetor]

#include<iostream.h>
class AnotherDate{
private:
int year;
int month;
int day;
public:
void setDate(int y,int m,int d){
year=y;
month=m;
day=d;
}
int isLeapYear(){
return (year%4==0&&year%100!=0)||(year%400==0);
}
void print(){
cout<<"year:"<<year<<",month:"<<month<<",day:"<<day<<endl;
}
};
void main(){
AnotherDate *date;
date->setDate(1980,3,1);
date->print();
}

编译能通过，但就是运行不起来，不知道怎么回事，希望大家帮帮我，多谢拉

#include <iostream>
using namespace std;
 
class AnotherDate
{ 
private: 
	int year; 
	int month; 
	int day; 
public: 
	void setDate(int y,int m,int d)
	{ 
		year=y; 
		month=m; 
		day=d; 
	} 
	int isLeapYear()
	{ 
		return (year%4==0&&year%100!=0)||(year%400==0); 
	} 
	void print()
	{ 
		cout <<"year:" <<year <<",month:" <<month <<",day:" <<day <<endl; 
	} 
}; 
void main()
{ 
	AnotherDate *date=new AnotherDate; //这里，分配内存空间
	date->setDate(1980,3,1); 
	date->print(); 
}

谢谢，我刚从java转到c++，晕了。。

[richbirdandy]

AnotherDate *date; //没有产生对象实例 date是个空指针


AnotherDate *date=new AnotherDate;

[mirsoft]

AnotherDate *date; 

//替换成AnotherDate *date = new AnotherDate
//或者AnotherDate date;
